    • PURPOSE:To realize the reduction of load to the researching capacity of an object searching sensor, the localization of a position after researching and the and the shortening in the analytical processing time of the motion of an object, by displaying an estimated object existing region after the object is lost in the estimated course direction of the object in an arbitrarily enlarged state. CONSTITUTION:When an object searching sensor 1 loses an object, lost information is inputted to a processing apparatus 2 which in turn erases the object position on a display apparatus 5. The apparatus 2 inputs newest searching information from a memory apparatus 3 and displays the position of an object directly before the lost of the object to the display apparatus 5. In this case, the apparatus 2 sets the resolving power (n) of a circle when calculates and displays an estimated object exisiting region and, next, if the analysis of the motion of the object has been performed prior to the lost of the object, sets a region theta1 one of n-divided regions on the basis of the analytical result to input the velocity of the object. When the object is lost before the motion of the object is analyzed, the course and velocity of the object are estimated to set parameters. The apparatus 2 calculates the estimated object exisiting region and allows the apparatus 5 to display the same.
    • 目的:实现对物体搜索传感器研究能力的降低,研究后的位置定位以及对象运动的分析处理时间的缩短,通过显示估计对象存在区域后 物体在任意放大状态下在物体的估计行进方向上损失。 构成:当物体搜索传感器1失去物体时,丢失的信息被输入到处理装置2,处理装置2又在显示装置5上擦除对象位置。装置2从存储装置3输入最新的搜索信息并显示位置 在这种情况下,设备2在计算时设置圆的分辨率(n)并显示估计的对象现有区域,并且接下来,如果分析 物体的运动已经在物体丢失之前执行,基于分析结果设置区域θ1为n个划分区域之一,以输入物体的速度。 在物体的运动被分析之前物体丢失时,估计对象的路线和速度来设置参数。 装置2计算估计的对象现有区域,并允许装置5显示它们。

    • PURPOSE:To realize with a simple circuit to prevent a equipment from causing malfunction when the abnormality of electric power source occurs, by so constituting that the abnormality of commercial power line is detected at a DC electric power source unit side in order to stop the operation of the equipment proper according to the detected signal. CONSTITUTION:A DC electric power source unit 3 is composed of a firm output electric power source part 5 and main power source part 6. The electric power source part 5 supplies electric power to a normally operating part 7 in a unit controlling part 4. If the normally operating part 7 requests for the operation of a main controlling part 8, its command 10 actuates the main electric power source part 6 to supply electric power source 11 to the main controlling part 8. On the other hand, an auxiliary electric power source 14, which is charged with the output of DC electric power source, is provided to the DC electric power source unit 3. The auxiliary electric power source 14 supplies reference voltage to an output voltage detection circuit 17 for detecting abnormal voltage. When detecting the abnormality of the electric power source, the detection circuit 17 outputs an operation stop signal to the unit controlling part 4.

    • PURPOSE:To secure the receiving operation of a modem against a fault such as the momentary breaking of a circuit, by sending a training control signal to the modem if a received signal is interrupted momentarily, and then stopping training operation. CONSTITUTION:If a signal being received is interrupted momentarily, a carrier detection signal CDi is also interrupted immediately in response to that, but a carrier detection signal CD is stopped a prescribed delay time later. Consequently, the AND circuit in the training control signal generating circuit of a control part ANDs the inverted signal of the CDi obtained by an inverter 11 and the signal CD in said delay time to start a timer 10 with the AND output, and then the timer 10 generates a prescribed-time output. In this case, the control part when discriminating the momentary interruption as real one generates a training control indication signal TCE. Consequently, the output of the timer 10 is used as a training control signal TC as it is. A modem receiing the signal TC is inhibited from performing training operation during the reception.
